It should reduce the probability of `broken pipe` or `connection reset by peer` errors in vmauth logs. * FEATURE: [vmauth](https://docs.victoriametrics.com/vmauth/): add auto request retry for trivial network errors, such as `broken pipe` and `connection reset` for requests to the configured backends. +* FEATURE: [vmagent](https://docs.victoriametrics.com/vmagent/): increase default value of `-promscrape.maxDroppedTargets` command-line flag to 10_000 from 1000. This makes it easier to track down large number of dropped targets. * BUGFIX: all VictoriaMetrics components: prioritize `-configAuthKey` and `-reloadAuthKey` over `-httpAuth.*` settings. This change aligns behavior of mentioned flags with other auth flags like `-metricsAuthKey`, `-flagsAuthKey`, `-pprofAuthKey`. Check [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/6329). * BUGFIX: [vmctl](https://docs.victoriametrics.com/vmctl/): add `--disable-progress-bar` global command-line flag. It can be used for disabling dynamic progress bar for all migration modes. `--vm-disable-progress-bar` command-line flag is deprecated and will be removed in the future releases.
